SOH CAH TOA
Sin Cos Tan
Remember O stands for opposite hypotenuse, Astands for adjacent (opposite angle) and H stands for hypotenuse (The longest side).
The main kinds are plane trigonometry and solid trigonometry. The latter will include trigonometry in hyper-spaces.

The wording of the question implies that you already have some kinds of trigonometry in mind and wish to know about others. However, you have not communicated which ones you do know about and we cannot guess that. As a result, we would not know whether our answer gives the kinds of trigonometry that you are already aware of or new ones. Consequently, it is not possible to answer the question with the amount of information it contains.
kinds of sets in college algebra?
Closed sets and open sets, or finite and infinite sets.
Two types of trigonometry are recognized: planar and spherical. Planar is 2-dimensional, while spherical is 3-dimensional. Though these are different fields, spherical trigonometry is really just an application of planar trigonometry in several planes.

Finite, countably infinite and uncountably infinite.
